I have a 2003 G35 Coupe with the following mods... Intake, Plenum Spacer, Osiris Tune. I want to keep the OEM exhaust but replace the Cats just to add a littler growl to it. I have been going back and forth about which ones to get. Any suggestions would be greatly appreciated.

 

Berks are great. They guarantee no check engine light and the most popular ones that we sell. In stock and ready to ship. PM me for details.

 

Had you used our Search function there's a good chance you would have read my opinion but since it cost me major $$ I don't mind making other members aware! I bought Berks HFC and enjoyed them for 7 or 8 months. Then I developed a rattle inside one of them that annoyed the crap out of me. Called Berks direct and they offered no help. I put up with the noise for a few more months and finally called them again after I'd had them for 13 months. Apparently they have a year warranty and even though I'd called them prior I was told I was "SOL!" (**** out of luck) Not wanting to return to OE cats I had a set of Fast Intention HFCs installed which was 3 years ago and they still sound great without issues! Gotta love how some vendors don't mind taking your $$ but offer zero help when you have issues!

Fast Intentions

Looking into some FI HFCs.

Are there any vendors here on site that sell at a discounted price?

$510 plus shipping is a bit up there lol

 

Hi Gary and thanks for the heads up on the Berks.. Since I live Atlanta and have to do the yearly emission testing, I was told that the Fast Intentions might cause the car to fail emissions. Also I was told that the Kinetix HFC is a good brand and would have no problem with passing emissions. Any thoughts on Kinetix HFC.
